The International Cricket Council has been working hard to draw more and more crowds for one-day internationals across the world. Except for the sub-continent, where you get massive crowds, and to an extent Australia, it's becoming difficult to draw spectators in huge numbers elsewhere. Accordingly, the ICC's brief to its Technical Committee was to come up with new ideas which could be incorporated so that the limited-overs game becomes more exciting for the public. The present system is more predictable, as very often, the result can be determined in the first fifteen overs of the game itself. The Technical Committee of the ICC, chaired by Mr. Sunil Gavaskar and comprising former international players like Angus Fraser (England), Tim May (Australia) and Arjuna Ranatunga (Sri Lanka) has recommended some innovations to liven up proceedings in one-day internationals.
Their first suggestion is to permit 'substitutions', as practised in soccer. A member of the main XI could be replaced after the match begins by a substitute who will be allowed to bat and bowl. The substitute could be brought on for a tactical reason, not just if there is an injury, and at any time. A batsman could be called in if he was scoring too slowly and replaced by a substitute. Similarly, a bowler can be called in if he is being smacked all round the park and be replaced by a substitute.
